When it comes to speed In a game of top trumps between human and machines they always win and that is because they have wheels. Wheels are less smelly and faster than feet thats a fact. So it is inevitable that some people would put wheels on a humanoid. Im really sick of cutting my toe nails over the years and think wheels would be a much better alternative. I say Humanoid but actually its so messed up looking i think it needs to be in a class of its own. a Backfront bendy twerker perhaps.
